עֹ֫מֶר

If you are harvesting in your field and forget a sheaf there, do not go back to get it. It is to be left for the foreigner, the fatherless, and the widow, so that the LORD your God may bless you in all the work of your hands.

When they measured it by the omer, he who gathered much had no excess, and he who gathered little had no shortfall. Each one gathered as much as he needed to eat.

Moses said, “This is what the LORD has commanded: ‘Keep an omer of manna for the generations to come, so that they may see the bread I fed you in the wilderness when I brought you out of the land of Egypt.’”

(Now an omer is a tenth of an ephah.)

“Speak to the Israelites and say, ‘When you enter the land that I am giving you and you reap its harvest, you are to bring to the priest a sheaf of the firstfruits of your harvest.
